This unique box provides an adjustable gamma
boost and cable driver optimized for HD-ready displays for full high-definition viewing.
Adjustable Gamma Boost: The Box1021 adds gamma adjustment to
RGB output devices for absolutely perfect shadow detail.
The Box1021's cable driver stage also lets you use an analog
output cable of any length. You no longer need to place the source near your TV! Perfect for those of you that
already have a long RGB cables installed.
The Box1021 is a simplified version of the Box1020
when not all of the features are required.
The RGB signal is passed through with no degradation in quality. It
works with any source that has an RGB output.
Box1021 is plug-n-play with no extra steps required. It can be used for all
standard High-definition TV formats: 1080p, 1080i, 720p. All standard frame
rates are supported.
This converter has a full dynamic range for maximum details in the picture
for all input modes. The converter introduces no missing black levels in the
output (no black crush) or washed-out whites.
Box1021 connects to your RGB display through a 15-pin D-Sub VGA connector or
through a VGA-5BNC break-out cable. Horizontal and Vertical sync information is
present in the VGA connector.
Low-Level Black Boost (LBB):
In most displays the shadow detail content is severely limited
or simply completely missing. When there are a lot of dark areas in the picture
they simply appear as a uniform black area even though the original content has
a lot of details within these areas. This phenomenon is next to impossible to
compensate by conventional means by simply increasing brightness or contrast.
By increasing brightness true blacks start looking grey and the
overall picture only becomes washed-out.
Box1021 LBB selectively addresses only the correct black (the
shadow detail) information of interest creating a very dynamic looking overall
picture with a rich shadow detail. The level of correction is adjustable for
maximum detail.
The following pictures show LBB in action. Look for black/dark
areas showing rich details using LBB. Brightness and contrast are kept the same
in all pictures and they are in their nominal settings for everyday typical use.
Only LBB is turned on/off. All pictures are taken with a regular camera 3 feet
away from the display.

Box1021 is the world's first stand-alone RGB to RGB Cable Driver to introduce the Low-Level Black Boost.

Demo Pictures:
The following pictures are examples taken with Blu-Ray player -> Box1021 -> NEC XG1351
CRT Projector. Low-level black boost is utilized in
all examples to bring out tremendous shadow detail. No photo manipulation of any
kind is done to any of the pictures except for resizing.
Long-Length Cable Friendly:
Box1021 has a dedicated cable driver circuitry that allows
cables of any length to be used to connect to your display. There is no need to
buy any extra equipment or to have Box1021 close to the display.

Reviews/Testimonials
"I received my Box1021 via express mail. The unit is a well
constructed device in cased in sturdy extruded housing. The printed wiring
board is built using modern surface mount technology with 3 connections, an RGB
in/out (HD-DB15) and a 9 volt power supply connection. The unit also has an
external adjustment for changing the level of gamma boost. I was only interested
in this feature so I will limit the scope of this review to that subject (see
my full review
and screenshots). Upon initial testing of the Box 1021 to the system the
first thing I wanted to test was bandwidth using a 1:1 pattern, it was important
to me the box did not degrade the signal to the projector. The bandwidth
requirements at 1080p@72Hz are very high with a pixel clock in the 210 MHz range
and is way beyond the rated specs of this projector so I cannot afford any loss
in of signal. See my
1-on-1-off test
patterns. No noticeable degrading of the pattern is detected. In
fact the ideal pattern should have equal brightness for vertical and horizontal
lines and with the Box 1021 the brightness is much closer to equal. This was a
nice unexpected side effect of the box. In short if your after a low cost
analog solution to boost your gamma the Box 1021 is hard to beat." -

"I calibrated the my Barco 800 projector with the BOX. The Black Boost level
is at around 25%. I now can see each different step from 0 to 5 IRE!! The
projector is so bright and on 0 IRE the room is completely dark. The contrast
and the depth in the picture are great. I'm a very happy man..." -
